BUTTON FOR SUIT-CASE LOOKS.

Specification of Letters Patent.

Patented Apr. 23, 1912.

T 0 all whom it may concern Be it known that I, LOUIS M. DYSON, acitizen of the United States, and a resident of New Britain, in thecounty of Hartford and State of Connecticut, have invented a new andImproved Button for Suit-Case Locks, of which the following is aspecification.

My invention relates to the button or finger piece'secured to and bymeans of which the bolt is moved, and an object of my invention, amongothers, is to produce an inexpensive button of this class, simple anddurable in its construction.

One form of device embodying my invention and in the use of which theobject above set out, as well as others, may be attained, is illustratedin the accompanying drawings in which Figure 1 is a side view of theface plate and case of a suit case lock with parts broken away to showthe button in central section and a portion of the face plate and casein section on the same plane, the lock mechanism, with the exception ofthe bolt, being omitted. Fig. 2 is a back view of the button. Fig. 3 isa view in section through the button on plane denoted by dotted line 33of Fig. 2. Fig. 4 is a view in section at right angles to the plane ofview of Fig. 1, looking down, the plane of section passing centrallythrough the button.

In illustrating my invention herein the lock mechanism, with theexception of the bolt, has been omitted as not necessary to a clearunderstanding of the invention, that resides in the button, theconstruction of the other parts of the lock mechanism and theiroperation being well understood by those skilled in the art.

In the accompanying drawings the numeral 5 denotes the case, 6 theclosing plate thereof, and 7 the hasp of a lock of ordinary and wellknown construction. In locks of this class it is desirable that theparts shall be of as light construction as possible, consistent withstrength, containing a minimum amount of metal. To this end I provide ameans for attaching the button to the looking bolt that enables thebutton to be formed of metal of minimum thickness, the shape of thebutton providing the necessary strength for the uses to which it issubjected.

In forming the attaching means, I make use of an improved attachment forsecuring the fastening plate to the button that makes use of the metalusually cut away to form the key hole, the process of uniting the partsenabling the attaching means to serve the double function of positioningthe fastening plate and for holding it securely in place and withoutrequiring the button to be formed of extra thickness to hold thefastening plate in position.

The numeral 8 denotes the button, of the usual cup shape having a keyhole 9, the round part of which is formed by displacing the metal toprovide a bur or hub projecting inward. The fastening plate 10 isprovided with a round hole of a size to closely fit over the bur or huband set closely against the inner surface of the button. A slot 11extends from this hole in the fastening plate, and the hollow lug isthen spun over against the surface of the fastening plate about the edgeof the round hole therein forming a lip 12 to secure the fastening platetightly and firmly against the inner surface of the button. The key hole9 is then completed by cutting a slot 13, slightly narrower in widththan the slot 11 in the fastening plate, this out being made by startingin the round part of the key hole and finishing at the end of the slot.In this operation a small port-ion of the lip 12 is forced along theslot into the space between the edges of the wider slot 11 and thenarrower slot 13, the parts so forced into this space constituting lugs14 that form a part of the sides of the slot of the key hole, theirproper function however being to hold the plate 10 against turningmovement on the hub, provided the lip 12 should not be sufiicient forthis purpose, as plainly shown in Figs. 2 and 3 of the drawings.

The fastening plate 10 is provided with fingers 15 the reduced ends 16of which form shoulders 17 which rest against one side of the lockingbolt 18, these reduced ends being turned over as at 19, thus holding theplate firmly against the shoulders 17 and 1s)ecurely fastening thebutton to the locking olt.

It will be seen that the means for securing the fastening plate iscomposed wholly of metal otherwise not used, the metal displaced fromthe key hole serving the double purpose of seating the plate firmlyagainst the wall of the button and also holding it securely from turningmovement thereon. The lugs for positioning the fastening plate andholding it against turning movement also form a portion of the slot ofthe key hole.

I claim 1. In a suit case look, a button having a hub formed from themetal displaced from the key hole and spun over to firmly secure afastening plate in place, the fastening plate fitting over said hub andhaving a slot to register With the slot of the key hole in the button,and fingers projecting from the fastening plate for the purpose ofsecuring the button to a locking bolt.

2. A button for a suit case lock having a hub formed from the metaldisplaced from the key hole and spun over to hold a fastening plate inplace, the fastening plate fitting over said hub and having a slot Widerthan the slot of the key hole 1n the button, lugs projecting from saidspun over portion into the space between the slot in the fastening plateand the slot in the key hole to hold said fastening plate againstturning movement, and fingers projecting from the fastening plate toform a securing means for securing the button to a locking bolt.
